Study Guide Answer KEY ! ! 1. Valves…! Tricuspid- between the right atrium and right ventricle ! Pulmonary-between the right ventricle and pulmonary artery! Mitral- between left atrium and left ventricle ! Aortic-between the left atrium and aorta ! ! 2. YOU DON’T NEED TO KNOW FOR TEST ! ! 3. ! Hypertension (hyper=too high) ! Hypotension (hypo=too low) ! ! High blood pressure measures the force of blood exerted on the artery wall. The two readings are the systolic pressure (top number) over your diastolic pressure (bottom number) when the heart relaxes. HBP is a reading of 140/90 where normal blood pressure should be below 120/80. ! ! 4. Sinoatrial (SA node) ! ! 5. is a RECORD used to measure the electrical changes in the heart muscle as the heart beats. ! ! 6. Arrhythmias= without normal heart beat (rhythm) ! AF= atrial fibrillation where the electrical impulses move randomly throughout the atria, causing the atria to quiver instead of contracting. ! VF= electrical impulse moves randomly throughout the ventricle, can cause cardiac arrest (complete stoppage of the heart). Death is likely to occur when VF occurs. ! ! 7. CHD= Congenital heart failure (when you are born with an abnormal heart) ! CHF= congestive heart failure (when the heart cannot pump enough blood). Usually caused by high blood pressure & coronary artery disease (atherosclerosis). ! ! 8. Similar to Question #3. ! Blood pressure is the force of blood exerted on the walls of the artery. ! See question #3. ! High blood pressure is dangerous because if means the heart is working harder than it should to circulate blood. This can lead to wearing down the walls of the artery, causing an aneurysm. ! ! 9. When someone is having a heart attack, two things can be happening in the body. In both cases, the heart is not able to pump the required amount of blood throughout the heart and body. ! 1. Fibrillation= hearts electrical circuit is disrupted leading to cause the heart to quiver= decrease in blood flow. ***Treat through defibrillation (machine to shock the heart, stopping it, and allowing the natural SA node to regain normal electrical current in the heart. ! 2. Cardiac arrest= when the heart is completely deprived of blood causing the heart to stop beating. ****Treat by CPR, compressing the heart with our hands to do the job that the heart can no longer do on its own. ! ! 10. Fuel line and transportation network for the CVS are: Arteries, veins and capillaries ! ! 11. Arterioles are small arteries, venules are small veins ! ! 12. MATCHING ! ! A. Heard at the beginning of systole= Lubb Sound ! B. Pacemaker= NO ANSWER BAD ANSWER CHOICE ! C. Low Blood Pressure= HYPOTENSION ! D. Swelling from fluid build up= EDEMA! E. Lead away from the heart= ARTERIES! F. Electricity within the heart=EKG! G. Inflammation of the lining of the heart=ENDOCARDITIS! H. move deoxygenated blood toward the heart=VEINS! I. Part in the heart where the heart attack occurred=INFARCTION ! J. Heard at the end of systole= DUBB SOUND! K. Inflammation of the membrane surrounding the heart= PERICARDITIS! L. Muscular Pump=HEART! M. Death of part of the heart tissue= NECROSIS ! N. Blockage by a clot=THROMBOTIC OCCLUSION! O. Abnormal heart rhythm=ARRHYTHMIAS! P. Weakening or widening of the arterial wall=ANEURYSM ! Q. Deposits of fat lining the coronary artery=ATHEROSCLEROSIS! R. Fuel line and transportation network=BLOOD VESSELS! S. Excessive Bleeding=HEMORRHAGE! T. Exchange of oxygen and nutrients into body cells=CAPILLARIES! U. Unable to pump the required amount of blood=CHF or CHD! V. lack of blood flow to the limbs, idiopathic=RAYNAUD DISEASE! W. SA node=PACEMAKER! X. High Blood Pressure=HYPERTENSION ! Y. Blood flow if decreased or stopped=ISCHEMIA! Z. The record of electrical activity within the heart=ELECTROCARDIOGRAM (gram=record)! AA. Bluish tint=CYANOSIS ! BB. Re-attached= ANASTOMOSED! CC. Swollen or twisted veins caused by damaged valves, causing blood to pool=VARICOSE VEINS ! DD. Surgical removal of plaque from lining of artery=ENDOARTERECTOMY (tomy=to cut) ! ! ! ***#22. Does NOT have a answer choice! It should be left blank. ! ! 1. 2. 3. 4. 5. 6. 7. 8. L P Z U aa R N S 9.
